Out in the islands, a cesspool or septic system is a common way of treating household sewage. Cesspools, however, are being phased out which leaves the property owner looking for alternatives. The first option that comes to mind is the simple septic system. This common treatment system uses a tank to hold the influent (solid waste) and a series of leech lines to spread the effluent (liquid waste) into the surrounding soil. This system is an improvement over the cesspool because the effluent is allowed to slowly percolate into the soil, away from the tank itself, and filter back into the local water table. With the cesspool, the waste is simply absorbed into the soil along the sides or bottom of the pool.The primary purpose of aerobic septic systems in Hawaii is to aerate the influent before it settles and packs down.
This process allows the enzymes in the septic system much better access to the many proteins left in raw sewage. The result is less sludge in the tank and a cleaner effluent to release into the lawn. This is useful when the tank is placed in a small yard or on property with hard soils. With large properties, using leech lines may be a viable option, but for homes where a small treatment area is required, aeration systems may provide a solution.Aeration systems spray the effluent in a fine mist over specific areas. The liquid may be mixed with chemicals to prevent certain toxins or improve lawn growth. Plus, the misting release only works for a set amount of time and usually on a specific schedule.
Keep in mind that all aeration systems vary by the site they are installed at. Soils can often affect the way effluent is filtered and a percolation test may be required.One benefit to selecting Aerobic Septic Systems in Hawaii is keeping the effluent release confined to specific areas. The soils can be tested for percolation (ability to absorb and filter liquid) and the best spot chosen for release. An extremely sophisticated system may allow the owner to select from various areas by switching valves. Selective release prevents any given spot from becoming too saturated and reduces the chance of killing plants.
